Millions of people suffering from diabetes mellitus may be spared the ordeal of pricking their fingers several times a day to test blood sugar levels, thanks to a breakthrough by University of Pittsburgh researchers who have developed a non-invasive method to measure the glucose level in bodily fluids.
Researchers Sanford A. Asher, Ph.D., professor of chemistry in the faculty and College of Arts and Sciences, and David Finegold, M.D., professor of pediatrics in the School of Medicine, created a thin plastic sensor that changes color based on the concentrations of glucose.
The sensor material, which would be worn like a contact lens, was described in a paper published in the online version of Analytical Chemistry on April 11. The paper is scheduled to be published in the print version of Analytical Chemistry, a publication of the American Chemical Society, on May 1.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
